Recently, Harbin Power Station Equipment Group Motor Factory Co., Ltd. independently developed the giant Francis turbine blade--Jinghong Power Station turbine blade passed expert appraisal and has mass production capacity. It pioneered the domestic mass production of giant turbine blades, indicating that China has the local manufacturing capability of giant turbines.
In recent years, China has vigorously developed and utilized water resources and widely used large hydro turbines to build large hydropower units. As the capacity of hydropower units continues to increase and their structural dimensions continue to increase, the manufacture of large and giant turbine blades is a key step in the construction of large hydropower units.
As the largest power station equipment manufacturer and power station engineering contractor in China, Harbin Electric Group has been relying on independent innovation for many years and has been tasked with manufacturing large generator sets for the country. The large electric motor research institute of Harbin Electric Machinery Co., Ltd., which belongs to the group, has previously adopted a new design method in the bidding of the right bank of the Three Gorges, and has made breakthroughs in improving the stability of the turbines of the Three Gorges generating units, completely eliminating the operation of the load pressure pulsating belt unit. Impact. This time, they began to develop the giant turbine blades of the power station according to market conditions. After nearly half a year of development and research, through the use of new technologies such as vertical pouring and back real and computer simulation technology, in early 2007, Harbin Electric Motor Co., Ltd. successfully developed a diameter of 8.3 meters and net weight. 9.46 tons of giant blades of the turbine unit of Jinghong Power Station.
According to the expert's appraisal, the main technical indexes of the chemical composition, mechanical properties, internal and external quality and dimensional accuracy of the Jingfeng turbine blades of Harbin Electric Machinery Co., Ltd. have reached or exceeded the manufacturing level of similar foreign products, and the developed methods have been developed. Innovative, with batch stable production capacity.
